public interface TargetDataStore
This interface is used to apply XLA update records from a source datastore to a target datastore. It assumes that the source and target datastore schema are IDENTICAL for the subject tables.
Method Summary | |
---|---|
int |
apply(byte[] updateDescriptor) Applies XLA update descriptor to the target datastore. |
int |
apply(byte[] updateDescriptor, boolean useCommitFlag) Applies XLA update descriptor to the target datastore. |
int |
apply(byte[] updateDescriptor, boolean useCommitFlag, boolean checkUpdateConflict) Applies XLA update descriptor to the target datastore. |
void |
close() Closes the connections to the datastore and releases all the resources in a timely manner. |
int |
commit() Use this method to perform a manual commit. |
boolean |
getAutoCommitFlag() Returns the value of autocommit flag. |
java.lang.String |
getConnectionString() Returns the connection string for this data store. |
boolean |
getUpdateConflictCheckFlag() Returns the value of the flag to check update conflicts. |
boolean |
isClosed() Use this method to check if this object is closed. |
boolean |
isDataStoreValid() Checks if the datastore is valid. |
int |
rollback() Use this method to rollback the last transaction in case of errors. |
void |
setAutoCommitFlag(boolean flag) Sets the flag for autocommit during apply. |
void |
setUpdateConflictCheckFlag(boolean flag) Sets the flag for checking update conflicts during apply. |
